That sounds like me. I have depressive episodes and I have lost interest in most things for years now. Just can't make myself enjoy anything. I get close at times but mostly I don't care enough. I, too, lost interest in religious services. I attend now because my better half pushes me. I interact a little and that's only so-so. It's just not the same anymore. Nothing is. Definitely, I think you should bring it up to your T and pdoc.
